Geotechnical Aspects of Underground Construction in Soft Ground comprises a collection of 112 papers, four general reports on the symposium themes, the Fujita Lecture, three Special Lectures and the Bright Spark Lecture presented at the Tenth International Symposium on Geotechnical Aspects of Underground Construction in Soft Ground, held in Cambridge, United Kingdom, 27-29 June 2022.
The symposium is the latest in a series which began in New Delhi in 1994, and was followed by symposia in London (1996), Tokyo (1999), Toulouse (2002), Amsterdam (2005), Shanghai (2008), Rome (2011), Seoul (2014) and Sao Paulo (2017). This was organised by the Geotechnical Research Group at the University of Cambridge, under the auspices of the Technical Committee TC204 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE).
Geotechnical Aspects of Underground Construction in Soft Ground includes contributions from more than 25 countries on research, design and construction of underground works in soft ground. The contributions cover:
- Field case studies
- Sensing technologies and monitoring for underground construction in soft ground
- Physical and numerical modelling of tunnels and deep excavations in soft ground
- Seismic response of underground infrastructure in soft ground
- Design and application of ground improvement for underground construction
- Ground movements, interaction with existing structures and mitigation measures
The general reports give an overview of the papers submitted to the symposium, covered in four technical sessions. The proceedings include the written version of the five invited lectures covering topics ranging from developments in geotechnical aspects of underground construction, tunnelling and groundwater interaction (short and long-term effects), the influence of earth pressure balance shield tunnelling on pre-convergence and segmental liner loading (field observations, modelling and implications on design).
Similar to previous editions, Geotechnical Aspects of Underground Construction in Soft Ground represents a valuable source of reference on the current practice of analysis, design, and construction of tunnels and deep excavations in soft ground. The book is particularly aimed at academics and professionals interested in geotechnical and underground engineering.
Mohammed Elshafie is an Associate Professor at the Department of Civil and Architectural Engineering at Qatar University. Prior to his appointment at Qatar University he was a University Senior Lecturer at the Laing O'Rourke Centre for Construction Engineering & Technology at the University of Cambridge. His research interest span large scale underground infrastructure assets and small-scale centrifuge modelling of underground construction activities with a strong focus on understanding actual underground structures performance during and after construction.
Giulia Viggiani is Professor of Infrastructure Geotechnics at the University of Cambridge. She has been involved in many major underground projects in Italy and the UK, including monitoring building response to construction of the Jubilee Line Extension in London and the design and construction of Lines 1 and 6 of Napoli Underground and of Line C of Roma Underground. She organised TC204 IS-Roma 2011 and was one of the three members of the Scientific Advisory Board of WTC 2019.
Lord Robert Mair is a geotechnical engineer who has specialised in underground construction in soft ground throughout his career. He is Emeritus Professor of Civil Engineering at Cambridge University, where until recently he was Head of Civil Engineering. Prior to his appointment at Cambridge in 1998, he worked in industry for 27 years, throughout which time he maintained and developed close links with the academic world. In 1983 he became a founding Director of the Geotechnical Consulting Group, an international consulting company based in London. He was appointed to the House of Lords in 2015.
